1994 968 Additional maintenance with ethanol fuel

Fuel System

Vehicle Information: Model(924/944/968): 968; Year: 1994; Body Type: Coupe; Total Mileage: 68000;

Has Porsche made, or have you, any suggestions re. additional preventive maint. for cars running fuel with 10% ethanol? Earlier fuel filter replacement is mentioned at the track, for example. How about hoses?On a related note regarding DE, we'd use 95 octane when it was available, otherwise 93, and felt the hp difference was noticeable. Now with 93 octane / 10% ethanol the degradation in hp also seems noticeable. Are there any additives that can restore some of the lost hp?
